Longitudinal assessment of growth velocity in relation to pubertal timing, IGF-I, fasting insulin and fat mass in healthy boys.

Puntos clave

• This research aims to examine the relationship between growth velocity, pubertal timing, and various biochemical factors in healthy boys.
• Longitudinal assessment of growth patterns in healthy boys.
• Measurement of growth velocity and peak height velocity (PHV).
• Analysis of hormonal levels, including IGF-I and insulin, and body fat.
• Comparison of growth metrics with timing of puberty.
• Early maturation linked to increased growth velocity and peak height velocity (PHV).
• IGF-I levels positively correlated with growth velocity.
• Shorter total growth period was observed despite increased growth velocity in early maturers.
